Title: Golf club
Inventor: ICHIKAWA SADAMU
IPC: A63B53/04
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent duffing and to enable straight swing even at the time of slow swinging by providing a roller having a rotary axis perpendicular to the moving direction of club head caused by the swing so that its lower part can be protruding from the bottom face of a club. SOLUTION: Concerning a golf club 1, a roller 3 having the rotary axis perpendicular to the moving direction of a club head 2 caused by the swing at the time of hitting a ball is provided so that its lower part can protrude from the bottom face of the club. Thus, since power to slide the head 2 to fall in the ground parallelly with the ground is operated, so-called 'duffing' is hardly generated. When the club head 2 is touched with the ground by the straight advancing property of the roller 3, power to rectangularly hit the ball with the club head 2 is operated. Thus, when swinging is performed along the roller 3 even in the case of slow swinging like putter, straight swinging is enabled.

Title: Surface analytic method
Inventor: TAKATSUKA TOSHIMOTO
IPC: G01N23/227
Filed: 1993-09-07
Abstract: PURPOSE:To analyze microregion on a sample using a scanning an Auger electronic microscope without damaging the sample by irradiating the microregion and the periphery thereof at a current density causing no thermal decomposition and then irradiating only the microregion with an electron beam having a reduced diameter CONSTITUTION:At first, a microregion and the periphery thereof are irradiated with an electron beam at such current density as causing no damage, e.g. thermal decomposition, on the microregion. In the final inspection for silicon wafer, for example, the current density is set at 50nA/mum<2> with the lower limit thereof being set at 2nA/mum<2>. The electron beam is spread over a region 10-20 times as wide as the microregion and the irradiation time is set in the range of 40-60 min. Shorter irradiation time causes insufficient formation of thin carbon film and longer irradiation time causes formation of a thick carbon film impeding the Auger spectroscopy. After irradiation over the wide range, only the objective microregion is irradiated with a focused electron beam. Since the thin carbon film protects the microregion and current is fed onto the thin film, temperature rise is prevented.

IPC: F16D35/00
Filed: 1988-09-30
Abstract: PURPOSE:To control a continuous torque transmission of good responsibility in accordance with temperature change by providing a spiral bimetal in a swirling room for a water pump to control in sequence a valve opening in association with its action. CONSTITUTION:A spiral bimetal 21 detects directly water temperature in a water pump (P) to move rotationally a valve plate 20 according to change in the water temperature for adjusting the opening of a return port 6, controlling the amount of a viscous fluid which is recycled from storerooms 4, 5 to an operation room 23. That is, when the calorific value of an engine is smaller and engine-cooling water temperature is lower, a rotational move of the valve plate 20 is made smaller and the opening of a return port 6 is made smaller to reduce the recycle amount of the viscous fluid to the operation room 23 for performing low-speed rotation of a fan with smaller torque transmission. As the engine-cooling water temperature rises, the opening of the return port 6 is made larger to increase the recycle amount of the viscous fluid to the operation room 23 for performing high-speed rotation of the fan. It is thus possible to control the rotating speed of the fan continuously and accurately.
